Inkplate10 black and white example not displaying after upload

TECHNICAL SUPPORT Inkplate

Customer:

I have Ubuntu 22.04 with Arduino IDE connected to my Inkplate10 board. The black and white example uploads successfully - the Arduino IDE log shows no errors and the upload completes. However, the board display does not change after upload. I’ve tried toggling the power button and disconnecting/reconnecting the USB cable, but the display still doesn’t update.

The upload log:

Sketch uses 357533 bytes (11%) of program storage space. Maximum is 3145728 bytes.
Global variables use 32032 bytes (9%) of dynamic memory, leaving 295648 bytes for local variables. Maximum is 327680 bytes.

Soldered Support:

The upload log is fine and the ESP32 on the Inkplate board has received the new code.

The issue is likely the board definition in Arduino IDE. There are differences between the e-Radionica Inkplate10 and the Soldered Inkplate10 that make code compiled for one version not work for the other. Check which board version you have by looking at the PCB color: blue PCB means e-Radionica, purple PCB means Soldered. The identification guide is here: Inkplate Arduino — Inkplate docs documentation

Try with the correct board definition in Arduino IDE. The basic black and white or grayscale examples should refresh the screen once you’re using the matching definition.

That was it - I was using the Soldered board definition, but I have the e-Radionica board. The example works now.
